Furthermore, the magnet piece manufacturing apparatus 310 includes a detection sensor 52 that detects the passage of the magnet piece 31 that is cut off and jumps out.
- the coating 34 is cut by the lowering of the second stage of the punch 43, the broken magnet piece 31 is bounced and jumps out in the transport direction. Thereby, the detection sensor 52 detects passage of the magnet piece 31, and the descent of the punch 43 is stopped. The protruding magnet piece 31 is received by the stopper 51, and the stopper 51 is retracted obliquely upward in the figure so as to be retracted from the conveyance path of the magnet piece 31.
- the coating 34 connected after the cleaving can be cut by the punch 43. Therefore, it is possible to prevent the production facility from being temporarily stopped due to the conveyance failure of the magnet piece 31.
- the punch 43 cleaves the magnet body 30 when the first stage is lowered, and then the coating 34 is cut when the second stage is lowered, the abnormal cracking of the magnet body 30 due to the overstroke of the punch 43 does not occur.
- the magnet piece 31 that is cut off and the coating 34 is cut off is received by the stopper 51, the magnet piece 31 can be prevented from being scattered and appropriately conveyed.
- the operation of the punch 43 is a two-stage motion.
- the magnet piece manufacturing apparatus 320 having the following configuration is used. It is also possible to adopt.
- the magnet piece manufacturing apparatus 320 causes the punch 43 to wait for a predetermined cutting time at the bottom dead center at the time of cutting.
- the cutting time is a time that allows the coating 34 to be cut reliably, and is set to 1 second, for example.
- FIGS. 14A and 14B The process until the magnet body 30 is cleaved is the same as that shown in FIGS. 14A and 14B (FIGS. 15A and 15B).
- FIG. 15C After the magnet body 30 is cut, as shown in FIG. 15C, while the punch 43 is stopped at the bottom dead center position, the bending force continues to act on the coating 34. Therefore, the punch 43 is further lowered as described above. Even if not, the coating 34 can be cut by waiting for the cutting time.
- the magnet piece 31 jumps out in the transport direction and is detected by the detection sensor 52.
- the standby at the bottom dead center position of the punch 43 is ended even if the cutting time has not elapsed.
- the coating 34 connected after cleaving can be cut by a bending force acting on the coating 34. Therefore, it is possible to prevent the production facility from being temporarily stopped due to the conveyance failure of the magnet piece 31.
- the detection sensor 52 detects that the coating 34 has been cut and the magnet piece 31 has popped out. Instead, a magnet piece having the following configuration is used. It is also possible to employ the manufacturing apparatus 330.
- the magnet piece manufacturing apparatus 330 attaches a load cell (load converter) 53 to the punch 43 and monitors the load applied to the punch 43 as shown in FIG. Further, when the load detected by the load cell 53 becomes equal to or less than the cutting determination load (for example, zero), it is determined that the coating 34 has been cut and the standby of the punch 43 at the two-step motion or bottom dead center position is terminated.
- a load cell load converter
- the coating 34 is cut by the operation of the die cushion 47, the conveying claws 48 and 49, or the punch 43 after the magnet body is cut.
- a heater 54 may be provided inside the punch 43, and the coating 34 with which the tip of the punch 43 abuts may be melted or burned off by heating the punch 43 when the magnet body is broken.
- the coating 34 connected after the cleaving can be more reliably cut, and the production facility can be prevented from being temporarily stopped due to the conveyance failure of the magnet piece 31.
- the coating 34 can be cut more reliably by adopting a structure in which the first to third embodiments are appropriately combined.
